If you guys are having a hard time playing multiplayer, then this is where gaming come's real. In multiplayer, there will be a lot of campers. to identify a camper in a room, throw in a flash-bang, or nova to draw him out. One perk helpful in this is the Tactical Mask. If you have that on pro, an enemy will be not only blinded and hurt, but you will be able to see his/her location when blinded.
If your dealing with guys that spawn trap, then the useful thing to do is hide in a small corner with a shotgun. they'll come to you and eventually you'll blast them at close quarters or you can have a claymore to put it near a (the only in-out door).
If your just getting hit with aircraft, have Ghost pro and the strella, and that should take care of it.
One last thing is, is that, if your dealing with good guys, the best class is to have either
Primary: Commando,Famas,AK, Enfield,AUG,Galil, AK74U,MAC11,Olympia,SPAS12,M60,PSG1,L96A1 Secondary: ASP,M1911,Python,Ballistic Knife, or China Lake Lethal: Frag Secondary: Nova,Concussion,Flashbang Equipment:Motion,Claymore,C4 Perk1:Ghost, Flak Jacket, Scavenger,Hardline Perk2:S.O.H.,Warlord,Hardened Perk3:ALL Attachmentsual Mag,Extended Mag,Red dot/Reflex Sight, Suppressor,Grenade Launcher
